Hi Kevin, first of all thanks for your help[/color]
You’re very welcome.
I see that Jens (jmozdzen) has a few suggestions that may help…
I see two different ways to resolve your problem:
- find a way to deal with a constantly changing IP address
- Find a way to prevent the IP address from constantly changing.
Most ISPs provide their customers a dynamic IP address but often this
is a PUBLIC dynamic IP address that permits traffic to be routed
across the Internet. When customers have multiple devices they wish to
use and the ISP provides only a single dynamic public IP address, a
router is used to assign a private IP address, often on the
192.168.1.0 network, to each of the local devices. The router
translates the assigned private IP address (192.168.1.x) to the public
IP address to allow each device to access the Internet using the one
public IP address.
I suspect this is what you have as you mention that your cellphone can
recognise a new IP address automatically. Since cellphones usually can
connect to a WI-FI network, this suggests that you have a router
configured to provide a local 192.168.1.0 network that can be used by
both wired and wireless devices. If this is indeed the case, the router
should have a web interface so you can configure the router. Most
routers let you configure the address of the private network, whether
or not DHCP addresses will be provided, and often you can specify
static IP addresses for specific devices.
If you can provide the make/model of your router, perhaps I could
provide additional information.
If it is impossible to configure a static IP address on your router for
your server, and you cannot make SAP work with the loopback address as
Jens suggested, you should still be able to configure a static IP
address on your server for SAP even if the router assigns your server a
dynamic IP address. This is not an ideal solution because it requires
additional server configuration so let’s look at what other solutions
are available first.

Thank you very much for both of you to have patient in order to guide me with a lot of details.
Well, I will try an option (not sure if it makes sense) in order to use my NOIP host name (fixed IP address) and then assign it to my router DDNS config. So therefore, I will fix this host name in the HOSTS file - SAP server which means it will be fixed even though the public IP address will be changed afterwards. On the other way, what I have been noticing is something related to IP conflict when it is changed, so I expect if I fix a NOIP host name perhaps it could avoid this conflict and fix my issue.
Whether my option described will not work, then I come back to you guys for deep dive into your guidance.
Well, again as I am very new in this infra-structure & network issues as well as Suse - Linux world, I am doing my best to share as much details as I can.
